This really.
As you can see from my sig, I have no problem running old bikes, in fact I actively avoid modern stuff.
I'll say the same thing as I say to all prospective owners of old stuff, before you buy, make sure you've got a reliable supply of reasonably priced parts; it's no good buying what you think is a cheap old bike, then finding out everything is NLA or double the price you're expecting.
They made a version of that bike for years, but don't forget the Japs like to make detail changes every year, so don't get caught out by some essential part that is prone to failure and unique to that year.
I would think your big issue will be, over that distance, your bike is barely going to get a chance to get warm, which is a killer; frequent oil changes will be on the cards. ____________________ Things get better with age; I'm close to being magnificent........

Am currently using an older bike to knock about between Maidstone & Chatham to socialise & such. Costs me peanuts to insure, about a tenner to fill the tank & no worries with scratching it etc.
To make it useable propperly;
* Pilot sporty's - Part worn £15 a tyre
* A new tube - £5
* Throttle cable £10
* Gearbox oil change - £5
* Plug £1.50
* Air filter cleaned & soaked in 80/90 gear oil £free
* Headlight bulb £3.50
Issues so far;
* Carb was jetted slightly lean & caused it to start heat seizing, which meant riding very slowly till it cooled. £1.50 jet and a decent clean of the carb saw this sorted.
* Cheaped out on changing the rear tube when i did the tyres. It went bang. Which is a pain in the arse as you cant use tyreweld on it to get you home, and i diddnt opt for breakdown cover.
* Headlight bulb pops every so often. However older bikes run 6v electrics, and no petrol station stocks a 6v 25/25W miniture prefocus bulb.
If you're up for the constant fiddling & playing around to get it running right then an older bike could be perfect, if not i'd be looking for the cheapest 50cc twist & go on gumtree.  ____________________ Please be aware that the above post may be full of complete nonsense.

Why? |
As I'm sure you know, it's not pressure that lubricates, it's flow; you can force oil round an engine at any pressure you like, but if it's too thick to get in the gaps it needs to fill, lubrication is impaired.
So, oil thins when it warms, there is an optimum temperature at which it's providing maximm lubrication, if it isn't allowed to get hot enough, it will never provide the lubrication it should.
In addition, the combustion process produces various byproducts (soot, condensation etc) that causes oil to degrade; some of those byproducts can be 'burnt off' and significantly reduced, if the oil is allowed to get to full operating temperature, for an extended period of time.
Engine oil that doesn't get to full working temperature and stay there for a while, degrades quicker, reducing it's effectiveness as a lubricant and a coolant, which is important in an air cooled engine.
If you look at modern vehicle service schedules, particularly those with the current vogue for headline grabbing "long life" intervals, they invariably class constant short distance use as adverse conditions and recommend much shorter oil change intervals, sometimes halving the time/distance between changes.
I'll spare you a Teffers-esque diatribe about my experience of ignoring those recommendations, suffice to say I've earned a tidy sum from rebuilding engines of a particular, city bound, fleet I look after, due to accelerated wear caused by insufficient oil changes. ____________________ Things get better with age; I'm close to being magnificent........

Z200 was a decent little runaround, I seem to recall. But there are about 5 left on the road for a reason Get a CG125 and be done with it. ____________________ The RXS100: vehicle of choice for Chuck Norris |

I'll be more specific.
Is it a "killer" to run a vehicle for (e.g.) 3 miles a day rather than 30?
To my dim comprehension, 30 miles would seem to be the same as the 3 miles, plus another 27 miles of wear. You get those same 3 miles of cold wear on either trip, and putting more miles on won't heal it, no matter how well lubricated.
If I change my oil at least every 6 months, regardless of mileage (and I do), and I put in longer runs when I get the chance (and I do), am I "killing" my engine by doing mostly short runs? ____________________ Biking is 1/20th as dangerous as horse riding.

I think its more the constant low mile run arounds that contaminate the oil with condensation and shit. It leads to increased wear due to less effective lubrication.
You may get the initial 3 mile wear, but rather than it stopping there, the oil gets to its far more engine friendly rate and removes the condensation and likely engine fuck up bi-products.
Thats my view on it, possibly wrong  |
